I remember buying Deathkeep, and it having the "honour" of being one of only a handful (two or three) games that I ever returned to the store on the grounds of being rubbish. Well, perhaps that is harsh, but it promised much, and delivered very little - was super disappointing.
My friend had dragonstrike, but it was so complex/fiddly/clunky that we gave up trying to play it. I'm sure some folks got to grips with it, but not us.
As others have said, it is very odd to release these individually, when none were particularly well received originally. I think the SpellJammer game mostly scored for novelty, but IIRC an interview with the programmer explained that it was super-rushed. Fantasy Empires might have been OK, although I think I'm confusing it with Fantasy General.
